RESEARCH

MATERIALS : The conversion efficiency of thermoelectric device is well defined by material factor so called as "thermoelectric figure-of-merit", Z = s S²/k, ﾊﾊ s : electrical conductivity, S : Seebeck Coefficient, k : Thermal Conductivity. Our researches are focused on development of materials which have high Z value and good understanding of the physics lying behind them. Bulk material such as skutterudite compounds, metal antimonide, chalcogenide, are current targets. An use of artificial nano-structure is another theme to realize superior thermoelectric materials.

DEVICES : Thermoelectric devices specially developed for power generation is one main theme of our group. To realize high durability and high efficiency, we test some unique modules which uses liquid metal for its inter-connects. ThermoPipe concept is another direction to realize practical thermoelectric cell.

SYSTEM : Our group have been contributed some domestic projects which aims waste heat recovery by thermoelectric
